Astro Trimless Round Fire Rated Fixed Downlight - Matt White

Each measures a neat 115mm deep and 79mm in diameter, with a cut-out diameter of 86mm. Once installed, the matt white finish can optionally be painted to match the ceiling colour for a truly inconspicuous effect.

Ideal for hallways, kitchens and offices, they have a waterproof IP65 rating that also makes them natural candidates for installation in zones 1-3 of a bathroom, including above the bath and inside a shower cubicle. They are also dimmable, enabling you to control the light levels in the room - fully bright in the kitchen or office where you want to stay focused, or turned right down for a relaxing soak in the tub.

These downlights are fire-rated for 90 minutes, which means that if a fire breaks out, they'll slow down its spread for that length of time before the ceiling collapses. They are also double-insulated, so they don't require a connection to electrical earth, making them suitable for older, pre-1970s buildings which lack electrical grounding.

Each takes a 50W GU10 'twist and lock' spotlight bulb, up to a 50W halogen rating or LED equivalent (sold separately), and the glass cover ensures a glare-free, even spread of light. They can be supplied as a 230V mains light or in a low voltage option.

Requires 1 x max 50W GU10 bulb, sold separately. For our recommended bulbs, see 'related products'.
